Subject: ASA-2 Durability and Performance Improvements
We are pleased to announce that all ASA-2 automatic slack adjusters manufactured on
and after April 7, 1986 (D0786F and up) will incorporate several improvements designed
to increase durability and performance.
1. The designed shoe-to-drum clearance has been reduced to provide a closer
adjustment and increased actuator stroke reserve. The ASA-2 will continue to use
the more reliable concept of shoe-to-drum clearance sensing rather than sensing
actuator stroke.
2. Changes in the design of the adjusting linkage assembly have been made to
increase its durability and reduce the possibility of breakage.
3. Improvements have also been made to the internal anti-reverse clutch mechanism
which will provide added durability.
ASA-2 assembly part numbers remain unchanged (refer to catalog pages 05-A-17 to
05-A-19). The improved version of the ASA-2 is totally interchangeable with the
previous version. Mixing of old and new versions on the same axle is acceptable. The
improved adjusting linkage assembly will carry the same part number as the older
version and is completely interchangeable. Other detail and subassembly replacement
part numbers remain unchanged also and may be used on both old and new versions of
the ASA-2 assemblies.
In addition to using the date code, the improved ASA-2 may also be visually identified.
